We let you know last week that The Cave would be added to the Instant Game Collection for PlayStation 3, replacing Dungeon Defenders, with either Tekken 6 on PSP (also PS Vita compatible) or Disgaea 3: Absence of Detention becoming the the PlayStation Vita’s latest free game, replacing Foosball 2012.

Well, it has been narrowed down and Tekken 6 is joining the PlayStation Vita’s IGC tomorrow. This means that Disgaea 3: Absence of Detention will be free on March 26th, as Plants vs. Zombies is leaving that day.

On the discount side of PlayStation Plus, a Hot Shots Golf: World Invitational ‘Course and Characters‘ DLC bundle, featuring three new characters (Kat from Gravity Rush is one of them) and three new courses, is going to be $8.99, 25% off the regular price of $11.99.

Rocketbirds: Hardboiled Chicken is then getting a 40% discount, making the PlayStation 3 version $7.19 (down from $11.99) and the PlayStation Vita $5.99 (originally $9.99).

Are you thinking of buying Rocketbirds at the cheaper price? Let us know in the comments below.
